Abstract

Research on the manufacture of lightweight brick with basic material waste processing of goldin the province of West Nusa Tenggara has been done. This research is very important because most of the people in NTB separate gold by amalgamation and cyanidation methods. Processes that do this will result in hazardous waste on the environment so that the need for countermeasures. The purpose of this research is to create a lightweight bricks made of waste processing of gold which has a strong press that meets national standards. This research was conducted through two stages, namely 1) Stage of light brick making, 2) Phase compressive strength test light brick production. The results showed that lightweight bricks made with waste raw gold processing and cement with a ratio of 3: 1 has a compressive strength of 7.80 kg / cm2. These results demonstrate compliance with national standards, namely 7.83 kg / cm2 so that the product of this research can be said to be feasible.

Abstract

[Title: Development of Lightweight Brick Based on Traditional Gold Processing Waste with Water Hyacinth Booster]. Research has been carried out on the manufacture of light brick made from gold processing waste with water hyacinth filler. The study was carried out by varying the direction of water hyacinth fiber as filler in light brick making. The direction of the filler is arranged in a horizontal, orthogonal and random direction. In each filler direction, the percentage variation of water hyacinth is arranged with the volume fraction 0%, 15%, 30%, 45%, 60%, from the total volume of the amount of light brick. The test results show that in the horizontal fiber direction the compressive strength is (2.43; 0.25; 0.54; 0.24; 0.50) MPa with a density (1.62; 1.34; 1.58; 1.42; 1.25) gr /cm3. In orthogonal direction the compressive strength was (2.43; 0.26; 0.80; 0.63; 0.77) MPa with density (1.62; 1.42; 1.49; 1.53; 1.42) gr/cm3. While in the random direction the compressive strength was (2.43; 0.73; 0.69; 0.59; 0.65) MPa with a density (1.62; 1.20; 1.41; 1.13; 1, 20) gr/cm3. From these data by comparing with previous studies, the most stable compressive strength and density values are formed in orthogonal directions. While the density value is most formed in random direction. In all directions the compressive strength and stable density were formed in the 60% volume of filler. The test results show that the light brick that is formed into the category is very light (entered in 0.6 - 1.6 gr/cm3 range) and floating in water, with medium compressive compressive strength.

Abstract

[Title: Making Chitosan From Shrimp Cup As Gold (Au) Adsorben]. This study aims to make chitosan from shrimp shell as golden adsorbent. Stages of chitosan preparation include demineralization stage using 1,5M HCL, deproteination stage using 3.5% NaOH to obtain chitin powder, then followed by chitin deacetylation stage using 60% NaOH to produce an anime that is chitosan. Subsequently, the chitosan obtained was characterized, analyzed functional group with FTIR and determined its adsorption capacity against Au metal ion, Au content in the sample before and after adsorption was measured using AAS. The results showed chitosan characterization as follows: rendeman 45.83%, have powder texture, white colour, odourless, have moisture content 1.55%, perfectly soluble in glacial acetic acid 2% and purple positive with ninhydrin solution showed chitin has turned into chitosan. Based on calculations from the results of the resulting chitosan FTIR data has a degree of deacetylation 71.17%. From the result of analysis by using AAS that chitosan obtained able to adsorb Au metal from concentration 8.55 ppm decrease until 5,09 ppm with adsorption percentage equal to 40.46%.

Abstract

[Title: The use of water hyacinth as a filler to improve the strength of lightweight brick making based on gold waste]. Research objectives is to testing the compression of lightweight brick. This research was conducted through three stages: Creating lightweight bricks (from waste mining of gold and water hyacinth) horizontally, orthogonally, and randomly. Characterization of the sample as follows: density, and compressive strength. The results show that the best compression analysis at low densities of light bricks horizontally, orthogonally and randomly in compositions: 70% GMW + 30% WH = 0.54MPa, 70% GMW + 30% WH = 1.18MPa, and 85% GMW + 15% WH = 0.73 MPa. Whereas, the density test horizontally, orthogonally, and randomly in composition variations of water hyacinth as follows: 70% GMW + 30% WH = 1.41gr/cm3, 3.40% GMW + 60% WH = 1.89gr/cm3, 85% GMW + 15 WH = 1.20 gr/cm3. It can be concluded that the filler composition is directly proportional to the compressive strength. In addition, the density is inversely proportional to the mass of the lightweight brick.
